This is all in regards to melee only.
PS: fix the range, revert it even. light slashes shouldn't reach as far as heavies, or hit someone your not even aiming at.
Dagger: add a global cooldown or something to that right click, as it stands you just hold W + R-click and your golden. just spam right click while your getting flinch-locked from a ps or fist, and you still have a solid chance of chipping their hp/killing them. add in lag and that becomes a high chance.
TB: not my area of expertise, dont know the in's and outs completely, but i feel that the charge time should be limited again, to dissuade from camping a spot for 5 minutes. would encourage people to charge when they get close, instead of holding it for forever.
BR: that left click has to go. the damage needs to be reduced and the attack speed needs to be reduced. as it stands your attack flies out faster than almost any other weapon, plus has a minor knockback, while chunking a solid portion of your hp. and they can do it again in almost no time. that's without comboing.
Fists: could use either a single one or combination of things like, reduced damage, slower attack speed on left click, lower stun time on jump attack, or just make it so you dont get flinched from the left click. as it stands your highly likely to just get slap boxed to death, and that's just versus one person. its like harder hitting PS lights. combine that with multiple people at the same time and your in for a bad time. people might say "just get a CS!". i don't feel like CS should be a requirement on every loadout, and should instead be a choice. don't really like the old love glove personally anyways.
Exo: should probably have a longer air time, or cost a chunk of sp for that right click.
Boots: not my area of expertise again, but should check into the ranges of some of the hits. that backflip kick from the jump attack combo hurts yo. could also be lag but eh.
other weapons seem to not be much of an issue as far as i can think at the moment. Sigma is over in the corner eating glue, Katana is commiting sudoku puzzles, and the vital is touching people against their will.
Fixing hitboxes, making them actually fit the player model and be smaller. i swear at the moment i feel like a giant walking egg. Another major thing, are the chip F skills. esper coat should have the same cooldown as beam, since beam is supposed to be a hard counter for it. as it stands blue is the go to, and really has too short of a cooldown. you could fight them and die, and by the time you respawn and get back to them, they could potentially be off cooldown for it again during that second fight. no bueno.
